EZRA A. MATI-IERS, 0E PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO DANIEL W. HARNER, OF PHILADELPHIA, PENNSYLVANIA.

ORE-CRUSHER.

To all whom it may concern:

Be it known that I, EZRA A. MATI-IERS, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Ore-Crushers, of which the following is a specification. v

My said invention consists of an improved construction of a crusher and pulverizer particularly adapted for pulverizing and crushing ores preparatory to smelting and refining, and it consists in various improvements in the details of construction and arrangement of parts whereby not only a very efiicient machine is provided for the purpose but one that is also comparatively inexpensive to construct and operate, all as will be hereinafter more fully described and claimed. Referring to the accompanying drawings which are made a. part hereof and on which similar reference characters indicate similar parts, Figure 1 is an end elevation of one of my improved crushers, Fig. 2 a horizontal section on the dotted line 22 in Fig. 1, Fig. 8 a horizontal sec tion on the dotted line 33 in Fig. 1, and Fig. A a. central vertical section on the dot-ted line lA in Fig. 1.

In said drawings the portions marked A represent the castings comprising the ends of the frame or casing of the machine, B the dust guards-or casing, C the bearings for the rocking crusher, D said crusher, E the stationary crusher, F the large pulverizing roller, and G, G and the small pulverizing rollers.

The frame of the machine comprises the end castings A, which are of suitable form and strength to aiford the required supports and bearings for the several parts.

The dust guards or casing comprises the plates B which are arranged across the end of the machine outside the small rollers G, G and G and also along the sides adjacent to the ends of said rollers and the large roller F. The end plate is supported on bolts 6 extending through a hook at its upper end and the ends A, and the side plates are connected thereto by flanges 7) riveted thereto, as shown in Fig. 2, and are otherwise supported by the connected parts of the machine.

The bearings O are suitable inwardly extending flanges on the upper ends of the Specification of Letters Patent.

castings A formed with suitable recesses to contain the rollers c, as best shown in Fig. 3.

The rocking crusher D is cylindrical in form and rests at its ends upon the rollers 0. Its interior is hopper-shaped and is lined with chilled steel corrugated plates D, which constitute crusherfaces. Said plates D have lugs d which engage with recesses (Z in the adjacent faces of the part 1) and thus secure said parts together. A slot d constituting a passage-way leads from the lower side of the hopper through part D and is adapted to discharge onto the side of roller F adjacent to the small roller G. At

each end of part D a downwardly projecting radial lug D is formed, each of which has a frame or slide secured thereto, said slides being each composed of vertical bars D secured at their upper ends to each side of the lugs D by a bolt (Z and at their lower end having a distance block D between them and secured together by a bolt (i which passes through each bar and said distance block. A sliding block D is mounted to slide vertically between said bars and a cam D mounted on the shaft 1, near each side of the machine, is mounted and adapted to operate in an opening provided therefor in said block. Thus, as shaft 1 revolves the frame D is vibrated back and forth and the crusher D is rocked upon the rollers 0, block D sliding up and down in the way between the bars D as will be readily understood.

The stationary crushing member E is a casting of the form best shown in outline by dotted lines in Fig. 1 and has a chilled corrugated crushing surface. It is supported by gudgeons c in each end which are mounted in bearings E formed on the lower ends of screw rods 6, which extend upwardly through perforations in flanges or on the ends of the castings A and are pro vided with nuts 6 on their upper ends to afford the means of support and adjustment. Other nuts 6 are provided under the flanges by which the rods may be held in any adjusted position and said crusher thus secured fixed in whatever position may be desired for the character of work to be done. Said gudgeons e extend through vertical slots a in the castings A, which hold said crusher from vibration, and permit its vertical adjustment. Dust guard plates 6 are mounted on said gudgeons to cover said slots, between the respective ends of the crusher and the adjacent casting A to prevent the dust and crushed ore from passing through said slots.

The crushing roller F is a large smoothfaced roller and is mounted upon the main shaft 1 immediately beneath the crushing members D and E. Said main shaft 1 is provided with a driving pulley 2 by which power may be applied by a belt from any source provided.

The rollers G, Gr and G are each mounted upon shafts journaled in bearings on the inner ends of rods or arms 9 which pro- 5 ject through flanges a on the castings A and have nuts g on their outer ends. A plate g is fixed to said rod 9 a short distance from the flange through which. said bolt passes and a coiled spring 9 is interposed between said plate and said flange, thus serving to normally force the roller carried by the inner ends of said rods toward the main crushing roller F. The several shafts of said rollers project through slots in the side plates B, which permit their adjustment. A casing 9 preferably surrounds each of said springs. By adjusting the nuts 9, said rollers may be adjusted toward or from the face of said roller F, as will be readily understood.

The carrier H is or may be an endless belt carrier of any approved form provided with suitable carrier flights and is mounted upon rollers h, h, on shafts suitably located to support said carrier beneath the crushing rollers. Its outer end is supported by a cable or any other suitable support H. The operation of my said invention is as follows The parts being in their respective positions, as illustrated in Fig. 1, the

ore to be crushed is deposited in the hopper and passes between the faces of the crushing parts D and E, the corrugated chilled steel surfaces D and E serve to break and crush the lumps of ore as the rocking member D is rocked back and forth by means of its connection with the cams D on the shaft 1. Said rocking member D is supported and its movements facilitated by the roller bearings 0 as before described. The crushed ore passes through the opening (Z which extends through the lower part of the member D and drops upon the surface of the crushing roller F and is carried between said crushing roller and the coacting rollers G, G and G by which it is pulverized and falls upon the endless carrier H beneath. Said endless carrier may be of any length or arrangement desired to carry so the pulverized material to the smelter or any other desired point. When it is desired to remove the roller F, it can be done by merely removing the belt wheel 2 and sliding said roller off the shaft 1 through c5 an opening in the casing B covered by a plate B which is secured in position by means of bolts o as shown. The bolts a? securing the frame D to the lugs D on the lower end of the rocking member D will also be removed in order to release said 7o frame and the cam from engagement and free roller F. The face of the crushers may be renewed when worn by lifting out of the supporting bodies and putting new parts in their places as will be readily understood. When it is desired not to pulverize the material the rollers G, G and G may be drawn away from the roller F so that the crushed or broken material will pass through without being pulverized. The degree of disso integration may be regulated by the adjustment of said rollers, as will be readily understood.

Having thus fully described my said invention, what I claim as new and desire to 5 secure by LettersPatent, is
